Hey Heisenberg,
To address issues raised, we do not have an official Irish server. We have servers #1 to #9, the restart times are located at the following address wasteland.arma.su
Day/Night has been tweaked, currently it updates the time a lot less than previously which causes less frame drops and freezes, however night time is currently too long it was supposed to stay roughly the same as before but with a nice smooth day to night transition.
The group issue is known and will be looked at.
Hope that answers your questions :)
